@jarobbins3 I agree. Graphical kinematic analysis has 2 parts- 1. Geometric Construction - Drawing lines, arcs; finding their intersections; measuring lengths... 2. Kinematics Reasoning - Knowing what to draw and how to use resulting lengths to find linear/angular velocities, accelerations etc. MicroStation makes step1 a breeze so one can focus better on the second half. One can construct parametric mechanisms and move them, add ‘flesh’ to make them more life like & even animate them in 3D!
@Mod Zedd Thank you for watching these clips and sending such enthusiastic feedback! It sure felt good to read it. Hope you are enjoying Kinematics as much as I do. Good luck!
@Shane Ellams Not sure if it is the best way of doing it, but I tried it with two vector loops: A-B-C-A and the other holding the tool (which is a simple slider crank). Both are triangles with a side of variable (hence unknown) length. Loop A-B-C-A can be worked out by eliminating the unknown angle (square and add the sine and cosine components) The resulting expression for length AC will be nothing but cosine rule! Next work out the angle and then move to velocities, acceleration etc.
For nearly 22 years i was in the industry and for the last 5 years i have been in academic line. Last year only, i started teaching kinematics of machinery. From that day on words, i have been going through your videos and learning a lot so that my teaching would be more and more effective. I should express my gratitude to you , sir. M.P. RAMA RAO.
mpramarao57 Thank you for that message Mr Rao. To say the least, I was touched to read it! I am glad you have taken your industrial, real life experience to the class - something our educational systems so dearly needs. I wish you and your students the best!
Hello, Im fascinated by these mechanisms. And I was wondering how one would be able to determine the vector loop equation of this specific Whitworth quick return mechanism. Thanks a lot!
thank you very much for your crystal clear explanation , nice simulation too :) .. really to learn this mechanisms from textbooks is really confusing.. for some mechanisms animation is not given NPTEL ... i'm happy that i found this :) :)
Sir, what here point c is rotating. But what we can say about motion of slider? Is it reciprocating here or it is just steady and move along with point c?
Abhinav Rai That's a great suggestion! In fact I had it planned when I did the first few videos and animated the radial engine. But then it just dropped out of my mind. Thanks for the reminder! Hope to get to it before I forget it again :-)
Respected Sri Rane, I shall be highly obliged if you could give me your email id, so that I may come out with a host of my doubts, which I think a person like you can clear. Please oblige

Tanx for your comments and in fact, i am trying my best to co-relate my industrial experience while teaching.
@sai trinath Animations can always make things livelier - especially for a subject like Kinematics. Glad you found it helpful. Wish you the best . . .

This has been of great help. The best video I have seen relating kinematics of machines. Thank you so so much. God bless you :)
+Rajat Khurana Thank you for those kind words! Wish you the best!
Once again, a splendid video Sir.. :) Thanx to u, i cud understand those traced circles.. :) Thanx.. :)
thank you very much for your crystal clear explanation , nice simulation too :) .. really to learn this mechanisms from textbooks is really confusing.. for some mechanisms animation is not given NPTEL ... i'm happy that i found this :) :)
I love u sir, your videos helped me a lot for preparing GATE....Thank you very much sir...
I felt so difficult while preparing but after watching this video I feel so easy...
thanku sir!!!
Glad to hear that! Thank you for writing back and hope the rest of the course here proves just as useful to you.
Wish you the best!
Sir, what here point c is rotating. But what we can say about motion of slider? Is it reciprocating here or it is just steady and move along with point c?
Respected sir, which software you have used to show this mechanism?
+Yogesh M I've used 'MicroStation' you can look up the link in the description.
sir i think that length of link AC&BC are increasing while rotating...anyways great videos ...
sir please add a animation for rotary engine which is also a second inversion of slider crank mechanism
Abhinav Rai That's a great suggestion! In fact I had it planned when I did the first few videos and animated the radial engine. But then it just dropped out of my mind. Thanks for the reminder! Hope to get to it before I forget it again :-)
Great work sir..
Thanks a lot ..
Thank you! You might like to watch the rest of the kinematics course. Wish you the best.
definitly..!!
sir thanks a lot.u are doing a great work.long live
Thank you for your kind wishes! Wish you the best!
1 new follower..👍👍
sir, ua xpaination was gud... do give an example for solving QRR also
Could you please give some more details like what is given and what is to be found?
Thank you Sir
My pleasure! Hope you'll enjoy the rest of the course too.
All the best!
thanks sir
Arun Kumar You are welcome! Wish you the best.
Respected Sri Rane, I shall be highly obliged if you could give me your email id, so that I may come out with a host of my doubts, which I think a person like you can clear. Please oblige
Ramaswamy Narayan I will be happy to solve the doubts here if I can. That way others following the thread can also benefit.
